A new technology focused subsidiary of American International Group will be headed by Seraina Macia, who was chief executive officer of Hamilton USA.

In May it was announced that AIG intended to acquire Hamilton USA, the US platform of Hamilton Insurance Group, in order to accelerate AIG’s application of emerging technology and data science to transform underwriting and claims.

The acquisition is expected to be completed in the fourth quarter, and Ms Macia will lead the newly acquired platform. She will also play an integral role in the accelerated development of Attune, the data- and technology-driven joint venture formed last year by AIG, Hamilton and Two Sigma Investments. Attune focuses on the $150 billion small commercial insurance segment.

Brian Duperreault, who founded Hamilton Insurance Group and became CEO of New York-based AIG in May, said: “Seraina brings to AIG a rare combination of deep insurance expertise and an acute understanding of the role that technology and data analytics are playing in the ongoing evolution of our industry.

“Her perspective will be a valuable one to have on our leadership team.”

Ms Macia was appointed CEO of Hamilton USA last year, prior to that she held executive roles at AIG. She will be executive vice-president and CEO of the new planned subsidiary at AIG and will also serve on the company’s executive leadership team.

She said: “It is great to be returning to AIG in this exciting new role. Brian has a clear vision for the future of insurance and for AIG.

“I’m looking forward to building on the progress we made at Hamilton USA in bringing technology and data analytics to risk selection, pricing and claims-handling processes.

“With AIG’s purchase of Hamilton’s US platform, we are poised to transform how our industry operates in a digital world and how we meet the needs of our clients. I look forward to being part of expanding and growing AIG during this next chapter in its history.”
